Effect of different angulations and collar lengths of conical hybrid implant abutment on screw loosening after dynamic cyclic loading.

Background: The purpose of this in vitro study was to evaluate the effect of different angulations and collar lengths of the implant abutment on screw loosening by measuring removal torque value (RTV) before and after dynamic cyclic loading using digital torque gauge.

Methods: A total 90 sets of 4.5 mm diameter × 10 mm length bone level implants with conical hybrid connection were used.

Acidic mammalian chitinase tuning after enteric helminths eradication in inflammatory respiratory disease patients.

Aim: This study aimed at investigating the presence of intestinal parasitic infections in inflammatory respiratory diseases patients during the disease attack, and measuring the acidic mammalian chitinase (AMCase) gene expression in blood before and after infection eradication.

Methodology: This case-control study included 123 inflammatory respiratory diseases patients and 120 apparently healthy individuals. Repeated stool examination was done, while total and specific IgE were measured.
